Question

How can I change mime type for uploaded files on Amazon S3. I have tried with http://docs.amazonwebservices.com/AWSSDKforPHP/latest/#m=AmazonS3/change_content_type but its not working.

Answer 1

You could try this:

// Instantiate the class
$s3 = new AmazonS3();

$bucket_name = 'my-bucket';
$file_name   = 'test1.txt';
$mime_type   = getMimeType($file_name);

$response = $s3->change_content_type($bucket_name, $file_name, $mime_type);

// Success?
var_dump($response->isOK());

function getMimeType($file) {
    // MIME types array
    $mimeTypes = array(
